CALEN DAR.

SPECIFICATION forming part of Letters Patent No. 409,526, dated August 20, 1889.

Application filed April 25, 1889. $erial No 308,576. (No model.)

To all whom it may concern.-

Be it known that I, FRANCIS M. UNDERHILL, a resident of the city of Brooklyn, Kings county, New York, have invented an Improved Calendar, of which the following is a specification.

The object of this invention is to produce a simple calendar that will hold from one to a dozen or more sheets, while permitting the ready changing of the sheets.

The invention consists in the combination of a frame having a glass front, with a springpressed follower that will press against and hold firmly one or more papers or sheets in the frame while permitting ready changing of the sheets.

Reference is to be had to the accompanying drawings, forming part of this specification, wherein- Figure l is a face view of my improved calendar. Fig. 2 is a crosssection of the same on the line a c, Fig. 1, showing a number of sheets in the calendar, and Fig. 3 is a similar view showing one sheet in the frame.

In the accompanying drawings, the letter A represents a frame that is provided with a glass front a. The frame A and its glass front a may be made in one piece of glass, as shown, or be of any other desired construction.

lVithin the frame A are placed sheets B of paper or other suitable material, upon which are produced any suitable inscriptionsuch as a daily calendar as in Fig. 1. I place twelve such sheets B in the calendar, each bearing an inscription for a diiferent month, the sheets being so placed that the inscription on the upper sheet can be seen through the glass front a.

In order to hold the sheets B properly and firmly in the frame A, I place a follower D within the frame which comes against the lower sheet of the pile of sheets B. The follower D carries a spring Z), that is pivoted to the follower by a stud (Z, so that the spring can rotate on the follower D. The ends of the spring I) pass into notches e in the inner walls of the frame A, whereby the follower D is held in the frame A and against the sheets B. The tendency of the spring I) is to push the follower D against the front a of the frame A, and when sheets B are interposed between the front a and follower D to hold said sheets firmly in position and against the front a. By means of this spring-pressed follower D,'I am enabled to hold a quantity to make up for the sheets removed. The follower will press against one sheet B, as in Fig. 3, as well as against a quantity, as in Fig. 2. When adjusting the sheets Bin the frame or removing them therefrom the spting b is turned to release it from the notches e, whereby the follower D can be removed, the sheets B adjusted and the follower then returned to its place to hold one or more sheets B. Instead of pivoting the spring 1) to the follower it may be disconnected therefrom while still pressing against the follower.

Having now described my invention, what I claim is- The combination of the frame A, having transparent front a and notches c, with the follower D, and the spring I), that engages the notches c, said follower being adapted to press against and hold a larger and also a smaller number of papers in the frame while permitting of their ready removal, substan- 8o tially as described.
